a simple git branching model

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

How to use rails load paths, app, and lib directories.

In Rails 3

NOTE: This post now lives (and kept up to date) on my blog: http://hakunin.com/rails3-load-paths

If you add a dir directly under app/

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.

If you add a dir under app/something/

My personal tmux cheat sheet for working with sessions, windows, and panes. `NB` I have remapped the command prefix to `ctrl` + `a`.

Sessions

New Session

  • tmux new [-s name] [cmd] (:new) - new session

Switch Session

  • tmux ls (:ls) - list sessions
  • tmux switch [-t name] (:switch) - switches to an existing session

A technical challenge we give to our Ruby on Rails applicants in order to evaluate their coding proficiency.Job description: http://www.alphasights.com/positions/ruby-developer-london or http://www.alphasights.com/positions/ruby-developer-new-york

Update: I no longer work for the company and this challenge is no longer used, but I'll leave the gist here in case people want to practice.

Alphasights Technical Challenge

Using Ruby on Rails we would like you to create a simple expert search tool. The application should fulfill the requirements below. The source code must be placed in a public repo on GitHub. The application should be deployable on Heroku.

  • I enter a name and a personal website address and a member is created.
  • When a member is created, all the heading (h1-h3) values are pulled in from the website to that members profile.
  • The website url is shortened (e.g. using http://goo.gl)
  • After the member has been added, I can define their friendships with other existing members. Friendships are bi-directional i.e. If Sasha is a friend of Ash, Ash is always a friend of Sasha as well.

  • Why do you want to join Google? -- Because I want to create tools for others to learn, for free. I didn't have a lot of money when growing up so I didn't get access to the same books, computers and resources that others had which caused money, I want to help ensure that others can learn on the same playing field regardless of their families wealth status or location.
  • What do you know about Google’s product and technology? -- A lot actually, I am a beta tester for numerous products, I use most of the Google tools such as: Search, Gmaill, Drive, Reader, Calendar, G+, YouTube, Web Master Tools, Keyword tools, Analytics etc.
  • If you are Product Manager for Google’s Adwords, how do you plan to market this?
  • What would you say during an AdWords or AdSense product seminar?
